Just got it a few days ago so as to give myself a lighter and more compact drill/driver for everyday use. I've already noticed that I have to remind myself to switch down from the higher RPM "drilling" setting when driving screws so that I get better control as the screw is entering the wood. It's fast and strong. It definitely has the torque to get the job done with only one hand but it accomplishes this without a lot of the painful wrist twists and occasional head-klonking from the earlier DeWalt 14.4v units. AS an example, I drilled three (3) 1/2" holes with a 16" speedbore paddle bit straight through well-aged 4" thick roof beams and a 3" deep 3/16" hole in dense poured slab concrete with absolutely no hesitation or difficulty. Along with that, a bunch of 3 1/2" screws. The drill/driver has good heft and yet is markedly lighter and more compact than my venerable 14.4v DW954 workhorse plus it fits the hand well and offers excellent balance. Since I already have DeWalt tools that use 7.2v, 14.4v and 18v batteries, the addition of 12v batteries doesn't phase me in the least since one model DeWalt charger will handle ALL of them. The ratcheting chuck is truly a blessing and holds round bits very well, especially since I had purchased, returned and reviewed DeWalt's DW926 9.6v model earlier on mainly because the bits slipped right out of that model's chuck regardless of how well I tightened the chuck. All-in-all, I'd have to say that this model from DeWalt is an excellent mid-range drill/driver with good speed and high torque for everyday professional use. Now, if you drive several hundred screws a day into dense wood decking, you might want something more substantial with larger batteries and greater torque. But for me, a professional handyman who encounters a very wide array of jobs with different requirements across different materials, the lighter weight and smaller size is a very big advantage -- all without sacrificing drilling and driving power.

Safety during DIY Tasks

Cordless drill drivers are significantly less hazardous than corded or electric power tools as there is no cord for you to trip or fall over. Cordless power tools are much more accessible than corded tools as they allow you go anywhere and work in places that would ordinarily be inaccessible due to there being no power plug. Cordless drill drivers are becoming increasingly small and compact in design and are extremely easy to move around and transport. However, the size and weight of a cordless drill driver may vary depending on the battery type. Technological developments have allowed power tool manufacturers to produce cordless drill drivers that have the same voltage and power capacity as electric corded drill drivers.

There are a lot of types of drill on the market place today, rotary drills, drill drivers, hammer drills, SDS drills manufactured for drilling brick, concrete, masonry, metal and wood. You can chose cordless or electric, when choosing an electric drill there are two voltages, 110 and 240. 110 volt power tools need a power tool transformer and are used mainly on building sites, 240 volt tools for home use should be used with a RCD circuit breaker for safety. Cordless drill drivers give more flexibility due to the fact that you do not have a mains lead to contend with.

An adjustable clutch is what separates electric from cordless drill drivers. Located just behind the chuck, the clutch disengages the drive shaft of the drill, making a clicking sound, when a preset level of resistance is reached. The result is that the motor is still turning, but the screwdriver bit isn't. A clutch gives you control so you don't strip a screw or overdrive it once it's snug. It also helps protect the motor when a lot of resistance is met in driving a screw or tightening a bolt. The number of separate clutch settings varies on the drill; better drill drivers have at least 24 settings. With that a lot of clutch settings, you can really fine-tune the power a drill driver delivers. Settings with the lowest numbers are for small screws, higher numbers are for larger screws. Most clutches also have a drill setting, which allows the motor to drive the bit at full power.

Cordless drill drivers are measured in volts. Drills are available in everything from around 2 volts (for a cordless screwdriver) to the newest 24-volt tools. Higher voltage means heavier weight so consider buying a tool that will meet 80-90% of your needs. Twelve to 14.4 volt models are the many popular, and they will usually meet many homeowner's work needs. Corded drills are measured in amps. Generally, a higher amperage motor means more power.

Lithium ion batteries are commonly used in consumer electronics and tools such as drill drivers. They are currently one of the many popular types of battery for portable electronics, with one of the best energy-to-weight ratios, no memory effect, and a slow loss of charge when not in use. In addition to uses for consumer electronics, lithium-ion batteries are growing in popularity for defence, automotive, and aerospace applications due to their high energy density. However certain kinds of mistreatment may cause Li-ion batteries to explode.

If a Li-ion battery is stored with too low a charge, there is a risk of allowing the charge to drop below the battery's low-voltage threshold, resulting in an unrecoverable dead battery. Once the charge has dropped to this level, recharging it can be dangerous. Some batteries therefore feature an internal safety circuit which will prevent charging in this state, and the battery will be for all practical purposes dead. In circumstances where a second Li-ion battery is available for a given device, it is recommended that the unused battery be discharged to 40% and placed in the refrigerator to prolong its shelf life. While the battery can be used or charged immediately, some Li-ion batteries will provide more energy when brought to room temperature.

Drilling a hole isn't rocket science but it can be quite frustrating should you don't know how to do it. For example, should you try to use a wood auger bit to drill a hole in metal you'll ruin the bit, score the metal and possibly injure yourself in the process. Drilling a hole correctly, however, is something you can easily accomplish with a little practice.

Not all holes need to go all the way through the material. Some holes need only be a certain depth in the wood. The easiest way to make certain you drill the correct depth is to measure the necessary hole depth on your drill bit. Then mark that point on the bit with a marker or wrap some tape around the bit at the measured spot. Then when you drill only insert the drill bit to the mark or tape. You can also purchase bit collars that slide over the bit and are secured at the appropriate depth. The collars usually attach with a small hex wrench or screwdriver. The drilling is done and you have to get the bit out. Give the drill a little power to spin the bit and slowly pull it out of the hole. Don’t be too fast or pull it out without spinning the bit. Either of these may cause the bit to bind in the hole. The hole is complete and now you need to attach the fastener. Bits can be inserted into the drill turning the drill into a screwdriver or wrench. If you are attaching screws determine the size of the screw head and select a matching screwdriver bit. Connect the screwdriver bit to the drill in the same way you would other drill bits. Put the bit head in the screw head and squeeze the trigger. Be careful not to provide so much power that you go all the way through the material (should that’s not called for) or pressure the screw head too far down into the material. It’s easy to get carried away with the power of the drill. If you are attaching a bolt fastener you can also purchase bolt sockets that can be attached to the drill. Match the bit size with the bolt, attach the bit to the drill, and screw in the bolt.

Also known as a wood or dowel bit, a spur point bit has a central point and two raised spurs that help keep the bit drilling straight. The bit cuts timber very fast when used in a power drill and leaves a clean sided hole. They are ideal for drilling holes for dowels as the sides of the holes are clean and parallel. Sizes range from 3 to 10mm. Spur point drill bits should only be used for drilling wood or some plastics. Sharpen the point and spurs with a fine file or edge of a fine grindstone; the angle between the point and spurs should be 90°.

DIY Safety tips:

Always unplug an appliance before working on it and always use the correct fuse for the circuit or appliance. Fitting a fuse of incorrect rating is dangerous. As an additional precaution, wear rubber soled shoes. This will provide a measure of insulation between you and the ground.
Always use the correct tools for the job. It is worth investing in high quality equipment as this will be safer and will probably do the job speedier.

Take extra care when removing artex or textured paint from walls as these materials may contain asbestos. Safety precautions must be followed when handling and disposing of asbestos. Contact your local environmental health department for advice.

New appliances have to be supplied with a plug that is fused in accordance with manufacturers' instructions. Always follow manufacturers' recommendations for fuses, or seek expert advice. Check older appliances such as electric blankets and Christmas tree lights. If a fuse blows for no obvious reason or an appliance is not working properly, switch off the appliance at the plug and unplug it before trying to find out why. The same principles apply to fuse boxes or circuit breakers - always switch off at the mains before you investigate and remember to replace the cover before switching back on. If you need to change a mains fuse, check the correct rating for that circuit - the blown fuse might have been incorrect in the first place. Using a thicker fuse wire than the correct rating is dangerous.

Always read the labels on materials to ensure that you know what safety precautions are required and action to be taken in the event of an accident. Many products give off harmful vapours. The recommendations regarding ventilation and/or respiratory protection should always be followed.
